Answer:

2x ^5 sqrt( 6x)

Step-by-step explanation:

sqrt( 3 x^4) * sqrt( 8 x^7)

Multiply them together

sqrt( 3x^4 * 8x^7)

sqrt( 24 x^ (4+7))

sqrt( 24 x^11)

We can simplify

sqrt(24) sqrt(x^11)

sqrt( 4*6) sqrt( x^10) sqrt(x)

sqrt(4) sqrt(6) x^5sqrt(x)

2 sqrt(6) x^5sqrt( x)

Combining the square roots

2x ^5 sqrt( 6x)

During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 7

kondaur [170]

Answer:

13 centimeters per day.

Step-by-step explanation:

We have been given that during summer, the water level of the river increased by 78 centimeters in 6 days. We are asked to find the water level increase rate in centimeters per day.

To find the water level increase rate per day, we will divide total increase by total days as:

$\text{Water level increase rate per day}=\frac{78\text{ cm}}{6\text{ days}}$

$\text{Water level increase rate per day}=\frac{13\text{ cm}}{\text{ day}}$

Therefore, the water level increase rate is 13 centimeters per day.

Which equation can be used to verify that 534 – 68 = 466?

IgorC [24]

Answer:

466 + 68

Step-by-step explanation:

We can easily check a subtraction problem with an addition problem.

Calculate the sum of the subtracted and the difference. If the sum is equal to the minuend in the original subtraction problem, the answer is correct.

Minuend - Subtrahend = Difference

466 + 68 = 534

The statement '534 – 68 = 466' is correct.

Hope this helps.
